A short, balanced and fully differential signal path supports a low noise design. Sealed relays ensure that signal paths remain free from distortion. The precision volume control uses a  studio-grade resistor ladder that ensures constant left/right balance at any level, and the bass management may be set to 80 hertz or full-range. Connectivity encompasses; 1 x balanced summed XLR sub output, 1 x stereo RCA plus XLR outputs together with 1 x RCA phono, 2 x RCA and 1 x XLR stereo inputs simplifying system integration with wired control available using the 3.5mm 12VDC trigger I/O.
